为探讨抽水蓄能电站上库抽水进流时库水流场变化情况,采用Standardκ-ε、RNGκ-ε、Realizableκ-ε三种κ-ε模型模拟分析了某抽水蓄能电站抽水工况时上库库区的流场,得到了库区流态图,并与设计阶段的水工模型试验结果进行了对比。结果表明,三种κ-ε模型均可模拟抽水蓄能电站上库抽水时的流场,尤其是Realizableκ-ε模型模拟效果最好。 In order to investigate the change of reservoir water flow field during the process of pumping in and out of the pumped storage power station, Standard κ-ε, RNGκ-ε and Realizable κ-ε models were used to simulate the pumping operation of a pumped storage power station The flow field in the reservoir area was obtained and the fluid state diagram of the reservoir area was obtained and compared with the hydraulic model test results in the design stage. The results show that all three kinds of κ-ε models can simulate the flow field of the pumped storage station, especially the Realizable κ model has the best simulation results.
